Part #: 3074P-B

Overview

The J&L Black Anodized Oil Separator is a precision-engineered solution designed to enhance the efficiency and durability of your Jeep Grand Cherokee or Dodge Durango’s 3.6L engine. By effectively capturing and separating crankcase oil vapors before they enter the intake manifold, this oil separator prevents intake contamination that can degrade fuel octane and reduce engine performance. It is specifically designed for passenger side installation, making it a direct-fit upgrade for 2016–2022 Jeep Grand Cherokee and 2016–2024 Dodge Durango models equipped with the 3.6L V6 engine.

Ideal for both naturally aspirated and forced induction engines, the J&L Oil Separator helps maintain a cleaner intake system, protects vital engine components, and supports consistent combustion quality for improved reliability and longevity.

Key Features

Built with advanced filtration technology and durable materials, the J&L Oil Separator offers reliable performance and easy maintenance:

• Multistage filtration system featuring a fine mesh stainless steel screen to trap oil vapors
• 1/2" thick, 1/16" aluminum honeycomb filter promoting vapor coalescence and efficient oil separation
• 3-ounce fluid capacity to collect condensed oil before it reaches the intake manifold
• Solid billet aluminum construction for exceptional strength and heat resistance
• Black anodized finish provides corrosion resistance and a sleek under-hood appearance
• Knurled tank base allows for easy removal and draining of collected oil
• O-ring seal ensures a leak-free installation
• Quick connect PCV fittings enable straightforward, secure installation
• Designed to reduce intake contamination and preserve fuel octane integrity

Construction & Design

The J&L Oil Separator is precision milled from a solid billet aluminum block, delivering superior durability and resistance to heat and corrosion. Its black anodized finish not only enhances longevity but also adds a professional, clean look under the hood. Internally, the separator combines a fine stainless steel mesh with a thick aluminum honeycomb filter engineered to capture even the smallest oil vapors, allowing only clean air to pass through to the intake manifold.

The unit’s knurled base design facilitates easy unscrewing for routine draining of accumulated oil, simplifying maintenance without mess. An O-ring seal guarantees a tight, leak-proof fit, preventing any unwanted oil or vapor escape during operation.

Installation & Fitment

Designed as a direct replacement for the passenger side PCV system, the J&L Oil Separator fits 2016 through 2024 Dodge Durango and 2016 through 2022 Jeep Grand Cherokee models equipped with the 3.6L V6 engine. Installation requires no modifications and utilizes quick connect PCV fittings for a secure, hassle-free setup. For optimal performance and to prevent overfilling, it is recommended to drain the separator every 2,000 to 3,000 miles.

Ideal For

This oil separator is perfect for Jeep and Dodge enthusiasts and daily drivers who want to protect their engine’s intake system from oil contamination. It is especially beneficial for vehicles equipped with forced induction systems such as superchargers or turbochargers, where crankcase pressures and oil vapor production are elevated. Maintaining a clean intake system with the J&L Oil Separator helps preserve engine performance, fuel efficiency, and overall engine longevity.

J&L Oil Separator Co. builds application-specific oil catch cans (air/oil separators) designed to trap blow-by vapors before they contaminate intake and intercooler plumbing. It’s a practical performance upgrade for boosted and high-output engines, helping reduce carbon/oil buildup and keep intake charge paths cleaner over time.
